Pollitt's Laminitis Images Have a New Look: MIMICS Software Goes 3-D

by Fran Jurga | 27 September 2009 | Fran Jurga's Hoof Blog

The cover of the Proceedings of the 2009 laminitis conference is a compilation of images of one foot of a chronic laminitis case from the University of Queensland in Australia. The foot's CT scans were converted to 3-D images using Mimics software and the expertise of Dr. Simon Collins of the Animal Health Trust in Newmarket, England. (Double-click on image for a larger view in a new window, but sorry that the web requires a low-resolution version of a very high-resolution form.)

When the end of the Fifth International Equine Conference on Laminitis and Diseases of the Foot comes, attendees might remember proportionately less of what they heard...and more of what they saw.

The heightened visual aspect of the exciting biennial conference, which will be held November 6-8 in West Palm Beach, Florida, may lie in the technology side of things, but the impact will be an eyeful that everyone can appreciate.

Leave it to Dr. Chris Pollitt (photo inset at left), assistant director of the conference, to bring the latest and greatest technology to the conference and to enhance his presentations.

The new software is called MIMICS; it is made by a Belgian company called Materialise NV. In a nutshell, MIMICS converts CT scans into three-dimensional forms. I've also seen it used to model a nasal cavity for a surgery case at Cornell's vet school, and for a comparative study of the soft tissue structures of equine feet at Auburn University. Dr. Pollitt says that MIMICS software is used extensively for human skeletal reconstruction surgery and prosthetic implant design and simulation.

"Suddenly I can 'see' an individual horse’s foot from all angles and can virtually dissect it on the computer monitor," Dr Pollitt wrote in the Proceedings.

MIMICS was introduced to Dr Pollitt and to the world of laminitis by British hoof anatomy researcher Dr Simon Collins. Dr Collins will be in Palm Beach to explain how he uses computer modeling in his work at the Animal Health Trust, where he collaborates with lameness experts Drs Rachel Murray and Sue Dyson. His images will be dazzling.

Dr Pollitt wrote in his introductory essay in the Proceedings, "Analyses of feet with chronic laminitis clearly show that distorted tubular hoof growth, lamellar wedge formation and solar loading of the distal phalanx are relentlessly destructive to bone. It behooves laminitis caregivers to understand the unmitigated, severe chronic process and develop proactive, early intervention strategies that will measurably arrest the process. MIMICS in the hands of laminitis scientists will aid this process."

Does anyone besides me see great irony in the way that Dr Pollitt over the years has created stunning visual images of the terribly destructive disease of laminitis? The quality of his images is always worthy of Scientific American or National Geographic and yet the subject is the disease we all dread. Thanks to his artistic eye we all know what laminitis looks like, even though it's the disease we'd most like to see wiped off the equine map.

NOTE: The deadline for registration for the conference has been pushed back to September 28th, since the mail has been so slow in getting the brochures and registration forms to everyone. Brochures were sent to all subscribers to Hoofcare and Lameness Journal. Also, a reduced rate for two-person registrations has been added. Visit www.laminitisconference.com for more information.
